vatvn LIFTER.

To all whom it may concern:

Be it known thatl, RALPH BROWN Goon- RICH, a citizen of the United States and a resident of the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Valve Lifters, of which the following is a full, clear, and accurate description, reference being had to the drawings, forming part of this specification.

My invention relates to lever-like devices employed for the purpose of lifting up valves in internal combustion engines to permit of the springs thereon being detached, preliminary to grinding. Such devices, known as valve lifters, have been provided in the past in a variety of forms and my invention has as its object the simplification of the mechanisms and improvement in modes o1 operation, in tools of this character.

Among other things it is my'object to provide a pair of j-aws, freely pivoting on the end of the operating lever and provided with means for adjustably holding them together, which means is on the jaws as distinguished from being on the lever.

This object and other advantages to be noted I accomplish by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings, 1

Figure 1 is a perspective view of the device in use.

Figure 2 is a perspective of the device on a larger scale.

Figure 3 is a plan view or". the jaw device.-

Figure 4 is a section on the line 4l4t of Figure 3.

While my i -ve tion plied to valvel scribed, I do not limited to this use tong-like features ditional uses.

The lever or bar 1 is provided in the valve lifter example of my invention which I have chosen as an illustration, and has a handle 2 and a toothed or serrated under edge 3. A chain 4 is provided, said chain having at one end any desired means for providing an engagement with some engine part. At its other end is a hook 5 which is adapted to engage the serrated lower edge a is adjustable 1920. serial in). 333,513.

.The jaw device comprises a pair-of jaw plates 6, 6, preferably having flanges or ribs 7 which are bent inwardly at'their upper and lower edges-to, form tabs 8 and 9,

that are perforated to engage a rivet-9 This rivet passes through a boss 10 at the end of the lever and provides'a pivot for the jaws.

The jaws swing on this pivot, both independently of each other for purpose of adjustment and simultaneously during operation.

The adjustment is provided by means of the rearward extension 11, 11, of the jaw plate flanges. The extensions are slotted at 12 and ears 13, 14 are formed at the top and bottom of the slotted portions. These ears have holes therein and nuts 15 are employed which are formed with pins 16, 17, extending from their upper and lower ends.

The pins are inserted in the holes in-the ears, thereby providing a pivotal mounting for nuts and the nuts are right hand and left hand threaded, respectively.

A right and left hand screw 18 isused which engages the nuts, and is operated by a fixed thumb piece 19, that lies between the jaw plate extensions, the screw being free of the lever.

With this construction the jaws maybe adjusted to engage any desired pieces, such. as the spring 20 of, a valve stem 21. The chain may be anchored to some engine part as at 22, the lever fulcrumed on the hook, the jaws engaged under the spring, and the spring and valve lifted to erator to disengage the spring from the valve stem.

The jaws may swinglto permit any necessary clearances for the lever and the whole structure is inexpensive and desirable.

Having thus described in invention, what I claim as new and desire to secure by Letters Patent, is

1. A device of the character described comprising a bar element, and a jaw element, means for pivotally mounting the jaw-element to swing laterally on the bar and means carried by the jaw element for adjusting the jaw opening thereof independent of the position of the bar.

comprising a bar element and a jaw elenient mounted thereon said jaw element made up 0%? two opposed independent jaw plates pivot-ally connected to each other and to the bar element to swing laterally and having extensions past means carried by the extensions for adjustv ably spacing them independently of thepi'w otal connection with the ibar element.

A device of the character described comprising a bar element, and a jaw element, means for pivotally mounting the jaw element to swing. laterally on the bar and means carried by the jaw element for adjusting the jaw opening thereof independently of the bar pivotal movement comprising" pivotally mounted members on the pivet point' and the aw members and a screw engaging said pivot'ally mounted membens whereby the pivotally mounted me alignment for engagen'ient with the screw iii all positions of the jaw element. v
